IMPROVEMENT IN MACHINES FOR CUTTING SHlNGLE-BANDS.

Specification forming part of Letters Patent No. 159,4?3, dated February 9, 1875 applicatien filed November 10,1874.

To all whom it may concern:

Be it known that we, J. W. BRITTON and F. L. CHAMBERLIN, of Cleveland, in the county of Guyahoga and State of Ohio, have invented new and useful Improvements in Shin gle- Band Gutter, of which the following is a description, reference being had to the accompanying drawings making a part of this specification, in which Figure 1 is a front view of the band-cutter. Fig. 8 is a plan view. Fig. 4 is a transversesection. Figs. 5 and 6 are detached sections.

Like letters of reference refer to like parts in the several views presented.

The object of this invention is to cut strips from a sheet of metal for shingle-bands.

The construction and operation of the machine are substantially as follows:

In the drawings, A represents a table or frame whereou is mounted a roller, B, having its bearings in the adjustable boxes C C. Oblique-1y in the face of the roller is secured a cutting-blade, D, Figs. 2 and 4:. Immediately back of the roller is arranged in the ways E E a gig-frame, F, the lower end of which is connected to the arms G G. The rear end of said arms are pivoted in the hangers H H depending from the table, as shown in Fig. 2. Projecting through the beam of the gig-frame are punches at a, two at each end, as will be seen in Figs. 2 and 4. Said punches are secured in the beam by setscrews 1). Under the punches is a perforated plate, 0, Figs. 5 and 6. The perforations therein correspond to the number and position of the punches, and into which the punches are received when in use. Extending across the edge of the table, directly facing the roller, is a bar, 0, Figs. 3 and 6, having a sharp cutting-edge, in concert with which the blade of the roller acts for cutting the strips. A vertical reciprocating movement is given by the gig-frame by means of the spring 0, Fig. 4, and the pins (1, Fig. 3, projecting from the ends of the roller.

The practical operation of the band cutter is as follows v A sheet of metal, from which the strlps are to be cut', is laid upon the table, and its lefthand edge adjusted against the guide H whereby the sheet is guided under the punches and cutters to the roller. The sheet thus laid upon the table is pushed forward until it strikes the body of the roller, the distance of which from the cutting edge of the blade D and edge 0 gages the width of the strip. Now, as the roller is made to revolve, the blade I), conjointly with the edge 0, cuts a strip from the sheet. During the time that the strip is being cut off, the gig-frame is forced downward by the pins d, impinging upon the upturned ends of the arms G G, to which the frame is connected, thereby driving the punches through the edges of the sheet, back of the blade for another band, while one band is being cut off, by which time the pins have become disengaged from the arms, and the gig-frame is forced upward by the reaction of the spring 0. The punched sheet is again pushed forward to the body of the roller, the blade whereof cuts another strip from the sheet, and so on until the sheet is cut up.

Strips of different width may be cut from the sheet by adjusting the roller nearer to or farther from the edge 0 of the table by means of the adjusting-screws h. This adjustment of the roller for the purpose specified will require that the blade D be set farther out from the face of the roller or nearer thereto, as the case maybe. By shifting the punches from the holes wherein theyare represented to the holes shown unoccupied, longer strips can be cut and punched, and still have the holes a proper distance from the ends for larger bunches of shingles.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. The gig-frame F, arms G G, spring 0, punches at, punch-plate c, and table A, in combination with the roller B and pins d, substantially in the manner as described, and for the purpose specified. 1

2. The adjustable roller B and blade D, in combination with the edge 0 of the table A, frame F, arms G, spring 0, punches at, and the table A, substantially in the manner as described, and for the purpose set forth.
